Polyvinylidene fluoride (PVDF) is commonly used in the chemical, electronic, and petrochemical industries because of its chemical and physical attributes. This study aimed to make novel PVDF-based composite with a high loading of silanized wood powder and micro/nanocellulose fibers, where glycerol acts as both a dispersant and a plasticizer all-in-one composite application for the first time. The purpose was also extended to systematically investigate their mechanical properties and melt flow. Results have demonstrated the efficiency of utilizing the cellulose fibers in bio-composites. With the addition of 30 wt% of filling materials, When the content of silanized cellulose fibers in glycerol dispersion is 25 wt%, the flexural strength and tensile strength reach the maximum value 72.30 MPa and 52.28 MPa. The experimental results indicate that silanized micro/nanocellulose fiber-reinforced PVDF/wood composites are a promising composite formula to help improve performance and reduce costs. It is an excellent example of utilizing biomass resources as a renewable/recyclable, sustainable and low-cost material to reduce the use of petroleum-based polymer, and improve the mechanical properties of composites.
聚偏二氟乙烯（PVDF）因其化学和物理特性，在化工、电子和石油化工等行业得到广泛应用。本研究旨在制备新型基于 PVDF 的复合材料，其具有高负载量的硅烷化木粉和微/纳米纤维素纤维，其中甘油首次作为分散剂和增塑剂应用于一体。本研究还旨在系统地研究其力学性能和熔体流动性能。研究结果表明了在生物复合材料中利用纤维素纤维的效率。当填充材料的添加量为 30wt%时，在甘油分散体中硅烷化纤维素纤维的含量为 25wt%时，弯曲强度和拉伸强度达到最大值 72.30MPa 和 52.28MPa。实验结果表明，硅烷化微/纳米纤维素纤维增强的 PVDF/木材复合材料是一种很有前途的复合材料配方，可以帮助提高性能和降低成本。这是一个利用生物质资源作为可再生/可回收、可持续和低成本材料的极好例子，可以减少对石油基聚合物的使用，并提高复合材料的力学性能。
